If there's an ammonia issue than a bubbler will do nothing to help. The fishes gills are basically burning....Also if it's Stress Zyme you meant, this contains NO b.bacteria...Live Bacteria has to be stored in a fridge and has a very short shelf life....If they look like there isn't enough air then throw a bubbler in for a little till everything is good again
